Range
(500 °C)
– this value must match the range set on the connected pressure
gauge. Exceeding the limits can be signalled as an alarm. The maximum range is
10,000 Pa.
Correction
(10 s, 0 Pa)
– consists of two parameters. The first one is used to smooth
the jammed signal from the sensor by specifying filtering in seconds. The first one is
used to smooth the jammed signal from the sensor by specifying filtering in seconds.
Press
(Pa)
– measured value of the current differential pressure from the connected
sensor. If the pressure value is below 0 Pa, then the supply cable has probably
shorted. If the pressure exceeds 10,000 Pa, then the supply cable has probably been
broken. A potential fault is indicated by a bell on the LCD display or a flashing or lit
alarm LED and a message in the alarm list.
Flow
(m3/h)
– indicates the current air quantity.
K–
factor
– used to calculate the flow rate from the measured differential pressure.
Relative humidity sensor
– in the
AssignmentInputs/Outputs
Humidity
menu, there for
the selected humidity, select one of the inputs marked according to the syntax described in
the previous chapter “Inputs and Outputs”, (e.g. for the humidity of exhaust air connected to
the 8th universal input of the fifth input extension, set
Extract
= 5X8
). Another option is to set
the humidity by setting the input to
Set
.
The required value for the required humidity is then
set under the
Correction
sign.
An example of setting the extracted humidity to a fixed value of
50% is done in two steps:
1.
Extract
= Set.
2.
Correction
= 50%.
Other parameters that can be set for any relative humidity sensor are:
Correction
(10 s, 0 %)
– consists of two parameters. The first one is used to smooth
the jammed signal from the sensor by specifying filtering in seconds. The other one
can be used by the user to change the value given by the sensor and make
adjustments to the relative humidity deviation according to local conditions.
Value
(%)
– indicates the current relative humidity of the connected sensor. If the
relative humidity value is less than 0%, then the supply cable has probably shorted. If
the pressure is greater than 100%, then the supply cable has probably been cut. A
